Question

NOt sure about this one

Answer 1

the normal inheritance pattern expected under independent assortment is not occurring. if there are only black-eyed black feathered and red-eyed white-feathered, the genes for feather color and eye color in crows are linked and do not follow independent assortment

Answer 2

and for the previous problem, independent assortment is the reason that it wouldnt end ujp with those certain conditions because they got assorted independently in their own spaces in a way

Answer 3

no, the point is that they did ~~not~~follow the law of independent assortment, otherwise we would have expected white crows with black eyes and black crows with red eyes. eye color and feather color are not inherited independently.

Answer 4

okay so following independent assortment basically gives you what you expect

Answer 5

And if it is not following independent assortment, you will get something unexpected

Answer 6

it's not that simple

if you observe the inheritance pattern of the crows, you will notice that eye-color and feather-color are not inherited independently, but rather, the traits are linked such that black feather color is inherited with black eyes and white feather color is inherited with red eyes

Answer 7

thus, we conclude that the alleles do not assort independently

Answer 8

OH okay I see that the black traits are linked in a way and the white are linked with the white

Answer 9

and because of that they do not assort independently because if they did , there would be a mix

Answer 10

yes

Answer 11

left is a and right is B?

Answer 12

yeah

Answer 13

oh right because they switch

Answer 14

but a and a go together I thought it was a and b

Answer 15

they're in metaphase so they need to be aligned along the midline such that each daughter cell will inherit one letter a and one letter b

Answer 16

wait I think I know what I did wrong for this

Answer 17

they're in g1 right now so the dna hasn't duplicated yet, so you would have to duplicate the dna first to get two copies of each chromosome

Answer 18

so 2 Aa's and two Bb's

Answer 19

yes

Answer 20

they don't all line up like that, they pair up in homologous pairs

Answer 21

blue is Bb and red is A a

Answer 22

sure

Answer 23

well they would independently assort

Answer 24

good just trying to figure out the rest

Answer 25

do you think they would maybe line up

Answer 26

Bad drawing but like that

Answer 27

no that's metaphase II

Answer 28

I know it's something like this just don't know how to represent this with your scenario

Answer 29

I can ask my professor tomorrow. No worries

Answer 30

but for part A would it be Aa Bb lined up together or AaAa

Answer 31

Aa + Aa since homologous chromosomes line up

Answer 32

GOt it. Thank you so much

Answer 33

Have a goodnight
